172 seventy-two weeks old layers were used to investigated the efficacy of organic acids on productive performance and reducing microorganism (salmonella spp. and E. coli) in faeces and on eggshell. The hens were randomly divided into 7 groups, each comprising five replications of 5 birds each: control, flavomycin in diet, organic acid 0.2, 0.4 and 0.6% in diet, and 0.1% organic acids solution type 1 and 2 in drinking water, respectively. They were fed 110 g/b/d for 6 weeks. The results showed that feed intake, egg production and feed conversion ratio were significantly difference (P<0.01) Feed intake of hens fed the organic acids solution in water were significant less than other groups (P<0.01). Egg production and feed conversion ratio of hens fed the organic acid 0.2% in diet was better than other organic acids supplementation groups and no significant difference with antibiotic group.
The total Salmonella spp. And E. coli counted in faeces and on eggshell at 42 day were significant less than the control group (P<0.01). These results suggest that organic acids supplementation in diet can be substitute as antibiotics and 0.2% in diet showed the best productive performance of organic acid supplementation groups.

The experiment on use of probiotics to replace antibiotics in broiler diets. A Completely Randomized Design (CRD) was used in the experiment. One day old Ross 308 CP broilers were weed 1 and the experiment composed of 4 treatments with three replications of 10 birds each for the total of 120 birds. Broiler were fed basal diets, basal diets with Lactobacillus, Bacillus and Antibiotic.
The result showed that chickens fed, Lactobacillus, Bacillus and antibiotic were significant better ADG and feed intake (P<0.05). But FCR and blood cholesterol were not significant difference (P>0.05). There data could be suggested that Lactobacillus and Bacillus can use substitute as antibiotics.

Agricultural commodity and food standards are used as references for manufacturing, trade, exports and imports and certifications, are rather done on voluntary than compulsory basis because people see the benefits of harmonization, their production standards to international accepted. However if necessities on consumer health or export competitiveness arise, they may soon be made compulsory. Although there are no existing laws demanding mandatory safety standards for food and agriculture commodity, ACFS can ask for cooperation from other authorized bodies to pass such laws. For instance, ACFS could ask the Food and Drug Administration to pass a law that specifies levels of toxic residues. However ACFS will always listen to opinions from all steakholders before it passes any standard, either voluntarily or compulsorily.
Any standard set by ACFS will cover all elements of safety and hygiene of human beings, animals and plants and qualifications of specific consumer product?s both food and non-food. Among standardizations are Good Agricultural Practice or GAP, toxic residues standards, and method for identification of animal disease. ACFS divides its standardizations into three categories commodity standards, practice system standards and general safety standards.
Commodity Standards are set as national references for production, domestic and international trade, and guarantees of products. The standards cover both safety and qualifications of products that consumers need or minimum qualification of basic agriculture commodities such as those of jasmine rice, durian, mangoes, asparagus, orchids, beef, pork, fish, etc. continue reading »
